Method and device for controlling deicing of refrigerator damper

Abstract

The invention provides a refrigerator air door deicing control method and device. The refrigerator air door deicing control method comprises the steps that a motor is controlled to drive an air door to move from the initial position to the target position; the driving current of the motor in the process of driving the air door to move is detected; first motion time of the air door from motion starting to motion finishing is detected; whether the air door has a deicing need or not is judged according to the driving current and the first motion time; and if the air door has the deicing need, a heating wire is controlled to heat the air door for a period of time equal to the preset heating duration, and the motor is controlled to drive the air door to move from the initial position to the target position. The refrigerator air door deicing control device comprises a motion control module, a current detecting module, a time detecting module, a need analysis module and a deicing control module. According to the scheme, the effect of deicing treatment on the air door of a refrigerator can be improved.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to a method and device for controlling deicing of a refrigerator damper. Background technique [0002] An air-cooled refrigerator is a refrigerator that achieves refrigeration through forced circulation of cold air. The low-temperature air in the refrigerator is forced to flow under the action of a fan, so that the temperature distribution in the refrigerator is even and the cooling speed is faster. The air-cooled refrigerator is provided with a damper, and the damper can automatically rotate with the change of the temperature of each compartment in the air-cooled refrigerator, so as to guide the cold air to different compartments, and realize the automatic control of the compartment temperature. [0003] With the use of the air-cooled refrigerator, the moisture in the refrigerator will condense on the damper, causing the damper to freeze. The damper after freezing will...

AI Technical Summary

Problems solved by technology

[0005] For the current method of defrosting the damper of the air-cooled refrigerator, the number and type of items stored in the refrigerator compartment are not fixed, and the quantity and water content of the items stored in the refrigerator compartment will affect the freezing speed and thickness of the damper. It will have a great impact. Using a fixed interval and a fixed length of time to defrost the damper may result in incomplete defrosting or an excessive rise in the temperature around the damper, resulting in a poor effect of defrosting the refrigerator damper.
